"Online Program to Enhance Teacher Learning to Develop Students' Information Literacy Skills" is an expected result from the implementation of Research and Development under the following concept: "It begins with teacher learning development. Teachers then incorporate the learning outcomes into student development." Firstly, as a result of implementing the R1&D1 to R4&D4 process, six sets of "Teacher Learning Manuals" and one "Teacher Workshop Manual for Implementing the Learning Outcomes in Student Development" were created. Secondly, in the R5&D5 phase, the manuals were evaluated with 157 teachers and 2,613 students using a one-group pretest/post-test experimental model in schools affiliated with the Office of the Basic Education Commission. The experimental results revealed that the teachers' scores on the post-experimental test had met the standard of 90/90, and that the mean scores had been statistically significantly higher than the pre-experimental test. Furthermore, the findings in implementing the teacher's learning outcomes in student development illustrated that their post-experimental mean score in the "Information Literacy Skills" assessment had been statistically significantly higher than the pre-experimental score. Taken together, these findings confirmed that the developed online program had been proven to be effective according to the established research hypothesis. Moreover, the study results also demonstrated that the developed online program could be distributed to schools under the Office of the Basic Education Commission.
